我们先后加工了几批铝合金高精度的圆球形零件(如图1)。圆球的不圆度要求不大于0.01毫米,圆球表面同内孔的不同心度不大于0.01毫米,光洁度▽12。零件材料为硬铝合金。由于实行了“三结合”,技术人员深入现场拜工人为师,充分发挥工人师傅的作用,这个问题较好地得到解决。二、圆球的铣削方法圆球加工通常是在铣床上铣削。零件装在分度头上,用硬质合金刀盘进行高速铣削。零 We have processed a number of high-precision spherical aluminum alloy parts (Figure 1). The roundness of the non-roundness requirements of not more than 0.01 mm, spherical surface with the inner hole of the heart is not more than 0.01 mm, finish ▽ 12. Part material is hard aluminum alloy. Thanks to the implementation of the “three unions,” technicians have paid in-depth visits to workers as teachers and given full play to the role of worker masters. This problem has been well solved. Second, the ball milling method Ball processing is usually milling on the milling machine. Parts installed in the indexing head, with carbide cutter for high-speed milling. zero
